|
|
The ``spi_led_strip`` light platform drives one or more SPI interfaced RGB LEDs. These LEDs are often used in strips, where
|
|
each LED is individually addressable. This component requires an SPI interface to be configured.
|
|
|
|
This component has been tested with APA102 LEDs and the P9813 LED driver. It should also work with HD107 and SK9822 type
|
|
LEDs, or any others with a similar interface - SPI, 8 bits per colour and BGR ordering.

# Example configuration entry
|
|
light:
|
|
- platform: spi_led_strip
|
|
num_leds: 30
|
|
id: rgb_led
|
|
name: "RGB LED Strip"
|
|
data_rate: 1MHz

Color Correction
|
|
----------------
|
|
|
|
It is often favourable to calibrate/correct the color produced by an LED strip light as the
|
|
perceived intensity of different colors will generally vary. This can be done by using
|
|
``color_correct`` to adjust the relative brightness of the RGB components.
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **num_leds** (*Optional*, int): The number of LEDs attached. The default is 1.
|
|
- **data_rate** (*Optional*): Set the data rate of the SPI interface to the display. One of ``80MHz``, ``40MHz``, ``20MHz``, ``10MHz``, ``5MHz``, ``2MHz``, ``1MHz`` (default), ``200kHz``, ``75kHz`` or ``1kHz``.
|
|
- All other options from :ref:`Light <config-light>`.
|
|
|
|
You may also need to configure an ``output`` GPIO pin to control power to the LEDs, depending on your hardware. The
|
|
APA102 and friends do not have a ``CS`` input, and are write-only so the SPI ``miso`` pin should not be specified.
